Dynamic generation algorithm of virtual ontology set in distributed ontology integration framework

为了有效组织和管理网格环境内存在的各类分布异构的本体资源,提出了基于网关服务的分布式本体集成框架。从体系结构角度对本体集成过程中涉及到的功能模块进行分析和划分,并基于网格服务设计了关键组件。在此基础上从提高计算资源利用率和满足用户多样性需求的角度出发,提出了虚拟本体集合动态生成算法。该算法将缓存技术与虚拟本体相结合,为本体数据的自动生成和再生成提供了较完整的系统方法,增强了本体资源的复用性。实验结果表明,该算法可以提高计算资源利用率,实现本体资源的复用率。

To organize and manage the distributed and Heterogeneous ontology resources in the grid environment effectively,a distributed ontology integration framework based on the grid service is presented.The function modules involved in the ontology integration are ex-tracted and the key components are constructed based on the grid services.To enhance the utilization of computing resources and satisfy diverse customers’ demand,a virtual ontology set dynamic generation algorithm is proposed.Combined with virtual ontology and caching technique,this method is used to generate and regenerate the ontology data automatically to improve the reusability of ontology resources.Finally,the validity and efficiency of the presented method is demonstrated by the simulation application.
